KNOW ALL MEN BY THESE PRESENTS:

That LJ. H. WALKER, of the city land county of Worcester, andCommonwealth of Massachusetts, have invented certain new and usefulimprovenients in Machines for Cutting Soles for Bootsand Shoes fromwhole sides of leather; and I do hereby deelarethat the following is afull, clear, and exact descrip'tienof the same, reference being had tothe accompanying drawings, forming a part of this specification, inwhich- Figurel represents a perspective view of my improved machine.

Figu're 2 represents a central vertical section, the line of sectionlbeing from front to back.

Figure 3 represents a top orplan view of one of the dies used to-cntseles for boots and shoes; and I Figure 4 represents a side view of thedie or cutter-shown in iig; 3.

The principalv object of my present improvement is to facilitate thecutting of soles for boots and shoes from i'vhole sides of leather, inaccordance with the patent granted to me on the 22d day of August, D.1865.

In the drawings, -A represents the floor or platform, upon which thelegs'B of the'machine, andthe supports C of 'theta'ble or plaforrn D,rest. E is .the lower part of the frame of the machine, the front lowersection or part Fy of which is removable, while the upper front' part Eis connected to the front box part G of the upper part H of the frame ofthe machine by a'neck piece H. The upper and lower parts E H are con;nected at the reai` by a'strong upright piece, I. In suitable bearings,a In, upon the part H rests and turns the main shaft J, from the head ofwhich projects the eccentric or crank-pin c, which receives the upperend of the connecting-rod or link d,'the lower end of -Which is hingedat e to the division piece'which unites the-side pieces gg, whichextendA up from the top of platen K, and serve as guides to retain saidplaten in ,proper position. l The side pieces gg are, fitted to slidewith a close it in the guide-box G, which connectsvsgith the neck pieceHf of the main frame. Platen K for convenience is not made solid, butwith an outer rim, h, comlbined with central or cross-ribs, e'. Betweenthe parts F and Ei are fitted four gears, two on each side. -These gearshave screw-threads cut in' them to fit four-screw-bolts or rods, whichpass through'the gears; The four screw-bolts or'rods pass up throughpieces F and E, andA are fastened securely7 to the bottom of thebedpiece or cutting-block L. The screw-bolts and gears on one side haveleft-hand screw-threads, so that when the screw-shaft or spindle M,which tits into all four gears-two on each side-is turned, the bed-pieceor cutting-block is elevated or lowered in a horizontal position. Thegears being fitted into slots when they are revolvedby the screw-spindleM, all the screw-bolts are elevated or depressed, together with thecutting-bloek L, so lthat the latter can be accurately adjusted nrespect to theplaten, whereby the leather can be cut by the die withoutthe edge of the latter being forced in to the face of theblo'ck orheadpiece. v

In lieul of the device abovei'descrihed for adjusting the bed', aninclined plane may be fitted betweenthe bed and frame E, so that whensaid inclined pla-ne is moved `by a screw, or otherwise, in onedirection, the bed will be elevated, and lowered when it is moved intheothery direction. Tlre upper part N of. the bed or cuttingblock isremovable, so that the face of this part ofthe block can be planed offwhen roughenedby much use.. The block is cut so. that the grain of thewood runs up and down. Upon the rear of shaft J' is placedabalance-wheel, J', to which is fastened thefdriving-pulley'O, both ofwhich run loose upon the end of shaft JQ- A. clutch, P, is placed uponvthe end of4 shaft J, the arms not of which pass through guides connectedwith pulley O an'd wheel J; a cap, o, on the end of shaft J prevents theclutch from slipping olf the shaft. Clutch l? is operated by the bentlever Q, fulcrumed at p, the long arm S extending under the frame E, andattached to the piece F by a spiral spring, x, as'fully shown in thedrawings. The actionA of the spring :v keeps the clutch and its arms n nback, so that shaft J and platen yK are not operated only when the frontend of the long arm S of the lever Q- is depressed so as to throw.clutch P forward, as shown inV red lines, fig. 2, in which case the armsn n are forced forward so vfar that they engage with the lugs or earsonthe huh z of shaft J. The screw spindle M may be made with a'threadcut only a few times around at the points where. the thread` engages thegears; the balance of the spindle may be left blank, and may be smallerfor convenience of manufacture. l

The operation is as follows: The operator takes the side of sole leatherand spreads it upon table D, the part where heldesires to commencecutting being placed under theplaten K. The'cutting-block or bed Lhaving been adjusted, he places the die T upon` the leather under theplaten, and then, with his foot, depresses the long arm S of lever Q,thereby throwing clutch P into operation, when motion is imparted to'shaft J, and the platen K is forced down upon die T, and a sole is cutfrom the whole side of leather. As soon as the cut is made the operatorremoves his foot from lever Q, and springs: causes the clutch to moveback, andshaft J stops by the time the-platen is elevated, as shown iniig. l. The operator now turns bis die and m0ves tl1e leather, ifnecessary, and the operation is repeated until the whole side of leatheris eut up, according to the mode secured to me by Letters Patent grantedon the 22d day of August, 1865.' By the use of the open and independentdie`1, the operator can place it 'wry quickly in the desired`po`sition,-while he can as quickly remove the die, and, by a suddenblow, knock out the cut soles. This lmachine has been pnt to a praticaltest with very important results.

Having described my machine for cutting soles for boots and shoes, whatI claim as new and of-my invention, and desire to secure by LettersPatent, is-

1. The combination and arrangement of the broad 'table D for supporti-ngthe side of leather, 'with the l adjustable bed or cutting-block L, andthe reciprocating platen K, substantially as and for the purposes setforth.

2. The combination and arrangement, with the table D, bed L, platen K,and shaft J, of the peculiarly constructed frame, composed of the partsmarked E H E and G, substantially as described.
